JOHN W. TEETZEL, OF URBANA, ILLINOIS.

WELL-DRILLING MACHINE.

T all whom it may concern:

Be it known that 1, Joan W. TEETZEL, a citizen of the United States, residing at Urbana, in the county of Champaign and State of Illinois, have invented certain new and useful Improvements in Nell-Drilling Machines, of which the following is a specification.

This invention relates to well drilling machines. One ob ect is to provide a comparatively simple, inexpensive, durable and efficient machine of the character stated.

Another object of the invention resides in the provision of a machine embodying such features that the drill may be driven charac teristic of the trip hammer principle as distinguished from those machines wherein the drill is raised and permitted byits own weight and the impact to cut and bore, wherebythe drilling of the well maybe more expeditiously accomplished.

A still further object of the invention is to so construct the drill and cooperating parts that the former may serve in the capacity of a pump for flushing purposes to carry off the debris by a continuously maintained flow of water without the use of auxiliary forcing means, such as an extra pump.

It is still further designed to embody in a drilling machine the necessary strength, compactness, very little friction, positiveness with respect to movement, a maximum of s eed and a free turn of the tools, without tie employment of belts, pulleys, chains,

sprocket wheels, ropes and sheaves, cones, ratchets, levers, etc., which latter form a prominent part in nearly all of the drilling machines now upon the market.

With the-above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter described, illustrated. in the accompanying drawings and particularly pointed out-in the appended claims, it being understood that changes may be made in the form, size, proportion and minor details without departing from the spirit or sacrificing any of the advantages t ereof. In the drawings:Figure 1 is a side elevation of my im roved invention. Fig. 2 is a lan view of t e walking beam. Fig. 3 is a orizontal sectional view of the machine below the walking beam. Fig. 4 is a front elevation, parts being broken away. Fig. 5 is a Patented May 19, 1908.

Serial No. 363,898.

' perspective view of a portion of the machine illustrating particularly the sectional front pipe connections mounted upon suitable supporting rails. Fig. 6 is a sectional view of the lower end of the drill rod and drill. Fig. 7 is a detail fragmentary view of the temper screw and certain of its cooperating elements. Fig. 8 is a detail view of a wedging member designed to assist in wedging the temper screw into engagement with the drill rod sections or for the connecting together of the sections composing the drill rods. Fig. 9 is a detail fragmentary view of the cross head, showing the collar embracing two part nut and stra ped to the cross head to prevent said nut from rotating. 1

Referring now more particularly to the accom panying drawings, wherein it will be seen that my machine is preferably of the wheeled ty )0, the reference character 1 indicates the side sills of the bed of the machine connected at their front and rear by the cross beams 2 and 3.

Mounted upon the cross beams are front and rear pairs of upri hts 4 and 5 respectively, the front upriglits being nearer together than the rear uprights and forming supports for the lower portion 11 of a derrick mast and the forward uprights ,44 are braced by the brace connections 6 and the rear uprights 55 by the brace connections 7. The rear uprights are connected at their u perends by a beam 8, while the u per ends of the front uprights are connected y a cast- I ing 9 to which latter the mast 11 is hinged as l at 12, whereby the mast may be folded down upon the machine when transporting the latter from one place to another.

Secured in the top of the rear u per cross beam 8 is a pair of eyes 13 designe to pivotall or hingedly receive the U-shaped hinge b0 ts 14 of the sides 15 of the walking beam whose sides converge toward and embrace the front uprights 4, extending slightly beyond the latter as shown. Each side member 15 of the walking beam has a bearing 16 at its forward end and depending from its under face for the rece tion of the trunnions 17 of one part 18 of t e head connecting the side members at their forward ends, the part 18 having a cooperating similar part 19,h1ngedly connected thereto, as at 20, with it's free end bifurcated to form spaced perforated ears 21, designed to embrace the perforated ear 22 of the part 18 whereby the parts of said head -without raising and lowering the latter.

may be locked together by passing a suitable key 23 through saidperforation. Each-part 18 and 19 is enlarged intermediate its end and provided with a semi-annular recess ada ted to embrace the two part nut 26 providied each upon its inner face with screw threads adapted to cooperate with the threads of the hollow tern er screw 27 hereinafter more particularly referred to. These parts of the nut, just alluded to, each have upper and lower flanges 28 and 29, respectively, to engage the upper and lower edges of the parts of the front cross head of the walking beam and are permitted to turn freely in the latter whereby the temper screw 27 may be turned in either direction, the nut turning with the screw When it is desired to raise or lower the temperin screw 27 for the purpose hereinafter explalned, the collar 28 upon the screw may be moved to embrace the lower end of the said two-part nut and held in engagement therewith by any suitable key 29, with a strap or other suitable means 30 engaging the collar and cross head to compel a raising and lowering of the screw by preventing the rotatable nut from turningin its cross-head. The screw operating handle 3O may then be grasped and the screw raised or lowered as may be desired.

Connecting the side members 15 of the walking beam are forward and rearward cross bars 31 and 32, res ectively, and these cross bars are connecte by a slotted supporting bar 33, the slot of the-bar 33 having a series of bores 33. and being designed to receive the upper end of the pitman 34 whose lower end is eccentrically mounted upon the driving shaft 35 jo'urnaled in any suitable manner u on the side sills l of the frame of the mac ine, the upper end of said pitman being pivoted by a suitable pin 36 disposed interchangeably in the aforesaid bores 33 of the supporting bar 33, whereby the upper end of the pitman may be adjusted toward or away from the forward end of the walking beam to increase or decrease the distance of its stroke or vibration.

To overcome unnecessary jarring of the Walking beam incident to the operation of the machine, I rovide a buffer or cushioning construction w 'ch may consist of a transverse supporting bar 37 disposed beneath the walking beam intermediate the ends of the latter, and slidably disposed for vertical movement between the vertical pairs of guides 38 secured in any suitable manner to the side sills 1 and braced by the aforesaid bracing connection 7, there being a second transverse cross bar 39 fixed between the uprights 38 for the support of the helical or other springs 40, upon which latter rests the aforesald transverse walking beam supporting bar 37.

The tempering screw 27 is secured to the hollow drill rod section 41 by the wedge devices 42 adapted to embrace said drill rod section and fit in the inverted conical shaped cups 43 fixedly carried at both ends of the tempering screw 27. These Wedge devices form substantially cone shaped members when arranged about the drill rod and preferably have their inner faces screw threaded, serrated, corrugated or otherwise roughened so that they may firmly grip said drill rod sec- 7 tion and prevent disconnection of the latter from the screw when both are raised and lowered. There may be any number of these'hollow drill rod sections coupled together depending upon the depth of the Well to be bored, another section being added after each sectionhas pierced the earth to the extent of its length, the temper screw having a bore of suiiicient diameter to clear the couplings of the drill rod as sections are added, and the temper screw is raised upon the rod for another operation, after having reached the limit of its downward feed. The upper end of the drill rod is swiveled at 45 in the elbow section 46 of the slush pipe, made up of telescoping sections 47, 4-8 and 49, the swivel allowing the drill rod to turn with relation to the slush pipe which only has a vertical movement. These telescoping slush pipe sections are slidably supported between the guide rails secured to the mast 10 by the pairs of links 51 through the instrumentality of the slidable nuts 52. The upper slush pipe spout will vibrate with the drill rod and telescope into the larger slush pipe 48, which latter remains stationary until the drill rod has been fed down into the earth the length of the temper screw, at which period the upper end of slush pipe 47 is on a level with the upper end of slush pipe 48. The 5 slush pipe 48 is now telescoped into the pipe 49 which allows the pipe 47 to move within the two as the drill rod gradually shortens by being driven into the earth. 1f

a new section of drill rod is added the slush 0 pipes'areagain extended and the swivel connected to the end of new sections, as shown in Fig. 5. The lowermost slush section 49 leads to a tank 53 having communications with the well 54 by Way of a suitable. pipe connection 55.

Mounted upon the driving shaft 35 is a, friction clutch 56 and by operating the clutch in one direction, the driving shaft may be revolved through the instrumentality of a driving pulley 57, to operate the walking beam through the instrumentality of the pitman connection 34 at any desired speed, say for instance, one hundred andtvmnty-iive vibrations per minute, the operator turning the drill rod and lowering the same gradually by turning the temper screw, for which latter operation the aforesaid operating handle 30 is provided. The motion for operating the various moving parts of the apparatus is applied in any suitable manner to driving puley 57. The drill or cutting tool end 58 of the lower drill rod section is hollow to permit the water to enter the drill rod, the water. carrying with it the sand, mud, rock etc.,'

loosened by the drill, forcing the water and debris into the drill rod and delivering the same to the slush pipe, the sand and rock precipitating into the bottom of the tank 53, and the water returning through the overflow pipe to the wall, whereby the water is used over and over again. The cutting end of the drill rod is provided with a ball valve 59 designed to prevent back flow of water and debris. The down stroke of the drill acts in the same manner as a pump, and the rapidity of operation causes a steady stream of water and the drilling products to be lifted up through the drill rod and the water returned to the well in the manner stated.

As shown in Fig. 3 the friction wheel 60 is normally out of engagement with the friction pulley 61, and is brought into frictional contact with the pulley 61, only when it is .de sired to use the winding drum 62 or the cat head 63, to wind or unwind a rope 64 which is passed over the pulleys 65 of the 'mast head 66 and attached to the temper screw, drill rod, or slush pipe sections, to elevate or lower the same, or for suspending such parts until the required connections are made therebetween, or new sections are added to the well casing or drill rod. The winding drum 62 is slidably mounted upon the shaft 66 upon which the friction wheel 60 is also mounted, and at one end it has a number of locking projections67 designed to engage the corres onding recesses 63 on the inner side of the friction wheel 60. A friction brake 69 engages one end of the drum and is controlled by a lever 7 0 connecting the brake by the link 71. This brake, is applied when the drum is free of the'friction wheel 60, so that the speed of the same may be controlled as the rope is unwound, and the drum 62 is shifted laterally into locking engagement .with the friction wheel 60 through the instrumentality of a suitable lever 72 pivoted intermediate its ends in the bearing 73 secured to the frame.

The driving shaft 35 is provided with a suitable balance wheel 74, and the winding drum shaft 66 has an eccentric bearing 75 operated by the lever 76 having connection -with the bearing blocks of the eccentric bearing through the instrumentality of the link 77. One end of the shaft 66 is mounted to have a little play while its opposite end is journaled in an eccentric hearing, as shown' in Fig. 1. The friction pulley 60 is brought into engagement with the drive friction by shifting'the eccentric bearing 75 in which one end of the shaft 66 is mounted, as juststated. It is necessary to move this shaft 66 by the eccentric mounting but a fraction of an inch to bring the friction pulley 60 in or out of engagement with the driving friction pulley 61.

From the foregoing it will be understood that as the driving shaft 35 is driven it causes a rapid up and down movement of the walking beam through the instrumentality of the pitman 34, the jarring occasioned by the reciprocation of the walking beam being overcome through the instrumentality of the springs 40. This rapid reciprocation or vibration of the walking beam causes a rapid up and down movement of the drill rod whose lower end cuts into the earth to loosen the soil and rocks, and by its impact forces the water up the tubular drill rod carrying with it the dirt, rocks, and other foreign matter and thence down the slush pipe toward the well, the dirt and rocks being separated by the water by precipitation into a tank with a return of the water to the well to be used over and over during the operation of the machine. It will also be understood that while the machine is running the tem- )erim screw is raduall Worked downwardly, giving a positive and powerful feed incident to the striking of a terrible blow.

It will be understood that the slush pipe sections may be added as required and that the drill bores its own way. It will also be understood that after the drill is in operation, the operator feeds down the drill by turning the temper screw say one-half inch. The result is that the drill can only penetrate the ground one-half inch. However, the drill works so rapidly that the feed may be practically continuous, sothat the same will penetrate say one-fourth inch at each downstroke. The feed will be varied'by the operator according to the nature of the soil. When boring through rock the drill would be fed very slowly. It will also be understood that I may test a well without the use of a separate pump.
